The 13-Five is perhaps our most comfortable goggle yet. The large lens format is a perfect fit over the brows. It's made with a multi-layer foam that's soft enough to wear for long hours. The spherical lens gives you a great distortion free view with totally unobstructed peripheral vision. The headband is made with a silicone bead to hold tight after adjustment. All 13-Five lenses are 100% UV blocking and impact resistant. This goggle comes with its own microfiber carrying case that can be used to clean the lens.
